Joint/Stereo Options

[TxHealer]

Forgive a terribly newbish question.

 

 

I'm trying to encode some wavs I have made into MP3 files. I've never had the joint option come up under stereo before. What is the difference between joint and stereo?

 

I need the left and right speakers to be treated individually (ie I need several instuments to only be present on the right side and not at all on the left- which is how the WAV is recorded.)

Ok, the terms "STEREO" and "JOINT STEREO" in Mp3's for example, refer to how the channel volumes are recorded.

 

It's a kind of difficult concept to explain but really all you need to know is that in Stereo audio there are two different channels being played at once, left and right and each of these channels will have different values as the sound levels fluctuate and the music is played.

 

In "STEREO" recording, two completely seperate values are stored and played through the two different channels, basically like this:

 

 

 

The "JOINT STEREO" is a much newer concept, however. It exploits the fact that a lot of the time, both channels have very similar signals and values being sent to them for playback and only records the difference from one channel as the values of the other channel.

Joint Stereo signal values are recorded something like this:

 

 

 

Except of course, it's much more complex than this, but this explanation was just to give you a basic idea of how the two methods differ.

Because of the way joint stereo works, it requires less bits to produce a certain quality level than standard stereo does.

You write: "Because of the way joint stereo works, it requires

less bits to produce a certain quality level than standard stereo does."

What happens when you choose for the "Joint" encoder setting?

Or the quality remains the same but the file size decreases, or

the file size remains the same and the quality is increased.

 

Can you give an URL where this is explained in more detail?

 

Can you take action, so that this gets in the help pages?

Do you have the paying versions? Which version?

 

Perhaps you also know what "Force" means. The sentence

about it in the help page clarifies nothing, it only makes the

mystery greater.

is joint stereo or stereo a better option for most mp3 players including older ones?

Hello,

 

I would suggest you use the highest quality files you can (dictated by your device) Do some research and find out what you can use.

The cost of storage is always going down, and there are an absurd amount of large, cheap playing devices around atm. For this reason alone, I leave my music files as closely to lossless as possible (flac if can)
